Background: Different techniques are used to measure skull base angle on sagittal images of MRI to diagnose platybasia and basilar kyphosis. Objective of this study was to determine the normal values of skull base angle using standard and modified methods of magnetic resonance imaging in Pakistani population. Methods: This cross-sectional, observational, descriptive study was conducted in Radiology Department, Wah Medical College, Wah Cantt. It comprised 700 subjects, including 336 females and 364 males (children and adults). Midline sagittal T1-weighted MR images were evaluated to measures the standard and modified skull base angles on Picture Archive and Communication System (PACS Links). All subjects underwent MR imaging on a 1.5 Tesla scanner, equipped with an 8-channel head coil. Data was collected on prescribed proforma and analysed using SPSS-23. Results: The standard MRI method gave a mean angle of 129.9±5.12° (range 108.1–148.3°) compared to mean angle of 121.3±5.06° (range 107.1–136.2°) obtained by the modified method; the difference of 8.6° between the mean angles given by these two methods is highly significant (p=0.002). Conclusion: Pakistani population has wider basal angle range as compared to the western population.
